Magnet moment

Although continuous wave NMR is sufficient for naturally abundant nuclei with strong magnetic moments such as hydrogen, fluorine and phosphorous, the study of low abundance nuclei and/or weak magnetic moments such as carbon 13 or silicon 29 requires pulse NMR. 

This is a single-magnet system with a magnetic moment parallel to the radiation surface for magnetic materials. The relative magnitude of the magnetic field at maximum from the height... 

The variation of magnetic moment s comer gives the effect similar to their lifting. The sum of corners is to be proportional to ... 

Double-magnet systems are the most convenient ones for transducers on non-magnet materials. In this case magnetic moments are the normal ones to a surface of the pattern and the opposite ones to the each other. The magnetic field fills the whole zone of the acoustic contact in such positions of... 

The curve allows determining the comer of a magnetic moment of one magnet (region 16 -i- 70 ). The comer of a magnetic moment of the second magnet is found as additional for comer proportional to (in + l)l80 , where n = 0,1, 2. Being calculated, this dependence is written as follows h... 

In addition, there could be a mechanical or electromagnetic interaction of a system with an external entity which may do work on an otherwise isolated system. Such a contact with a work source can be represented by the Hamiltonian U p, q, x) where x is the coordinate (for example, the position of a piston in a box containing a gas, or the magnetic moment if an external magnetic field is present, or the electric dipole moment in the presence of an external electric field) describing the interaction between the system and the external work source. Then the force, canonically conjugate to x, which the system exerts on the outside world is... 

Because the neutron has a magnetic moment, it has a similar interaction with the clouds of impaired d or f electrons in magnetic ions and this interaction is important in studies of magnetic materials. The magnetic analogue of the atomic scattering factor is also tabulated in the International Tables [3]. Neutrons also have direct interactions with atomic nuclei, whose mass is concentrated in a volume whose radius is of the order of... 

Therefore, in NMR, one observes collective nuclear spin motions at the Lannor frequency. Thus the frequency of NMR detection is proportional to Nuclear magnetic moments are connnonly measured either...

If the angular momentum of a free electron is represented by a spin vector S=(S, S, S ), the magnetic moment... 

Classically, the interaction energy of a magnetic moment pg in an applied magnetic field B is... 

The transition between levels coupled by the oscillating magnetic field B corresponds to the absorption of the energy required to reorient the electron magnetic moment in a magnetic field. EPR measurements are a study of the transitions between electronic Zeeman levels with A = 1 (the selection rule for EPR).
